    ffmpeg, how to record a webcast sound

    I was using a following command to record a webcast (video+audio):
    Code:
    ffmpeg -f alsa -ac 2 -i pulse -f x11grab -framerate 25 -video_size 1920x1080 -i :1 -acodec pcm_s16le -vcodec libx264 -crf 0 -preset ultrafast ScreenCast.mkv
    To my great disappointment, it also recorded all sounds picked up by the microphone, which totally ruined the webcast recording.

    Is it possible to instruct ffmpeg to record the audio stream but not the microphone?

    The solution = pavucontrol can be used to select the recording source; in my case it is 'Monitor of Built-in Audio Analog Stereo'
    By the way, the menu appears only when the recording is started, otherwise nothing is there to select. This is my screenshot...
